Reference for Pesachim 8:1
הָאִשָּׁה בִּזְמַן שֶׁהִיא בְּבֵית בַּעְלָהּ, שָׁחַט עָלֶיהָ בַּעְלָהּ וְשָׁחַט עָלֶיהָ אָבִיהָ, תֹּאכַל מִשֶּׁל בַּעְלָהּ. הָלְכָה רֶגֶל רִאשׁוֹן לַעֲשׂוֹת בְּבֵית אָבִיהָ, שָׁחַט עָלֶיהָ אָבִיהָ וְשָׁחַט עָלֶיהָ בַּעְלָהּ, תֹּאכַל בִּמְקוֹם שֶׁהִיא רוֹצָה. יָתוֹם שֶׁשָּׁחֲטוּ עָלָיו אַפֹּטְרוֹפְּסִין, יֹאכַל בִּמְקוֹם שֶׁהוּא רוֹצֶה. עֶבֶד שֶׁל שְׁנֵי שֻׁתָּפִין, לֹא יֹאכַל מִשֶּׁל שְׁנֵיהֶן. מִי שֶׁחֶצְיוֹ עֶבֶד וְחֶצְיוֹ בֶן חוֹרִין, לֹא יֹאכַל מִשֶּׁל רַבּוֹ:
A woman — so long as she is in her husband's house — if her husband slaughtered for her and her father slaughtered for her, she eats of her husband's, [so long as she did not specify that she wished her father's. For it is assumed that she wishes to be numbered with her husband's.] If she had gone to spend the first festival [after her wedding] in her father's house, [this being the custom] — if her father slaughtered for her and her husband slaughtered for her, she eats where she likes. [This, in an instance where she had not been in the habit of always "running" to her father's house until now, so that we are in doubt as to her preference.] An orphan for whom caretakers slaughtered [If he had two caretakers and each numbered him for his Pesach], he eats wherever he wishes. A bondsman of two partners eats of neither. [For who granted that the one's half be numbered with the other? There is no amendment for him unless the two agree that he be numbered with one of them.] One who is half bondsman-half free does not eat of his master's, [but of his own. For since the halachah is that we compel his master to write him a writ of emancipation, even though he has not yet been freed, he is regarded as freed and eats of his own.]
